I have used a Mackie DFX12 for 8 years... "knock on wood" I've never had an issue.

When looking for new speakers a few months back, I listened to the QSC K10, EV ELX112P, and the RCF ART 310a. Bang for the buck, the RCF won on all fronts. I liked the QSC K10 second but it was a bunch more money. The EV was light but doesn't sound like the other boxes they make. I did like the ZXA1 800w but it didn't have enough low end to me. The RCF 310a was under $400 and I couldn't pass on it. I got my pair from Washington Music in MD. Ask for Nate in Pro-Audio.
